Along with many naturopathic doctors and nutritionists, we believe the RDA for K2 is woefully low at 100mcgs. This is stone age level thinking. Just this week the Mayo Clinic came out with a major report on the power of K2 on non-Hodgkin’s Lymphoma.

The body needs far, far more than 100mcgs a day. Also, there is zero toxicity for K2 even at levels way above the 200mgs we use. So it is totally safe at high levels.

We use what we know the body needs. If I could use more I would. The Japanese use 45mgs for their Osteoporosis drug which is pure K2 and nothing else, and have had zero reports of any toxicity or any complaints and quite the reverse as it has incredible effect on major osteoporosis.

However as some people worry about toxicity we are updating the D3+K2 formula to mirror the amount the Japanese use, plus adding several important co-factors to increase the potency of both D-3 and K-2.

If you have any further questions or concerns, please get back to me ASAP.

Kind regards,

Dr Garland

If I not mistaken I read in many places that the RDA is 100 mcg (0.1mg). The strength you mentioned is 200 mg , is this not an over dose of
200 000%. I am worried that high strength of Vitamin K will lead to major toxicity.

As I stated in our newsletter report, a flurry of new studies suggests that vitamin K may help combat cancer. Vitamin K1 appears to play a role in cell replication, transformation, and survival, and can inhibit cell growth.

Vitamin K2 encourages the suicide (apoptosis) of pancreatic and ovarian cancer cells, while vitamin K2 analogs induce the same kind of programmed cell death in leukemia cells. These preliminary reports suggest that vitamin K may one day be used to “instruct” cancer cells to stop their dangerous, unregulated growth.

The studies I recommend everyone access and read thoroughly are listed here and re-affirm my strong belief that Vitamin K-2 deficiency is the root cause of many of the primary cancer conditions we are fighting today.
